I have a character with all the standard setup made by PHAT, but there aren’t individual bodies on things like fingers, or arm/leg twist bones. It seems like animations continue to play on bones that have no bodies associated with them, but physics work normally on bones that do have bodies.
I’m not sure if this is a recent bug since all the tutorials and info I’ve been finding tell me that if you enable physics on a mesh, its animations should have no influence.
